Here's the Driven Sprocket and Slider. Chain - go X or O-ring?

[the Ferret]

Ptero like anything else in this world... tires, oil, filters, air filters, there is no one concensus. I googled it and the manufacture claims longer life, less rolling resistance etc etc for the X ring chain. Members of various forums however can't agree on this with some stating from worse to no longer life up to same and longer life. Or as my brother likes to say "This is the best/worst thing I ever bought, it's the noisiest/quietest, the least/longest wearing, runs true to size/order the next (pick one) larger/smaller size, totally waterproof/leaks like a sieve etc etc product per the reviewers.

Try an X ring, and in 5 years report back. What have you got to lose? It's only money.
